Microsoft Security Update for DigiNotar Certificates

Microsoft Security Advisory 2607712 has been updated to revoke the trust of the DigiNotar root certificates by placing them into the Microsoft Untrusted Certificate Store.

The update is available via Automatic Update and applies to all supported releases of Microsoft Windows, including Windows XP, Windows Vista, Windows 7, Windows Server 2008, and Windows Server 2008 R2.

Copied below are the known issues from Microsoft KB Article 2607712, Microsoft Security Advisory: Fraudulent digital certificates could allow spoofing for this update. 

Known issues

• A restart is required for all editions of Windows XP and of Windows Server 2003.
  
  
• A restart is not required for all editions of Windows Vista, of Windows 7, of Windows Server 2008, and of Windows Server 2008 R2. The installer stops the required services, applies the update, and then restarts the services. However, if the required services cannot be stopped for any reason, or if required files are being used, this update will require a restart. If this behavior occurs, you receive a message that advises you to restart.
  
  
• At the explicit request of the Dutch government, the release of this update on Windows Update will be delayed for the Netherlands.
  
  This update will become available to the Netherlands on Windows Update and on all Automatic Update channels at a later date. Customers who want to manually install this update should click the appropriate platform download in the "Download information" section.
